Dec. 29, 1890, marked a bloody end to the U.S. military's struggle with the Plains Indians. U.S. forces massacred 146 Sioux, many of them women and children, at Wounded Knee in South Dakota.

Many Native Americans at the Pine Ridge reservation believed that by rejecting the new American culture and practicing the Ghost Dance, the gods would recreate their world and the non-believers would perish. The Ghost Dance movement's influence made the U.S. government nervous. The conflict at Wounded Knee began when the U.S. Army sent in a cavalry to surround a group of Ghost Dancers and collect their weapons. A fight broke out between a soldier and an Indian, and once one shot was fired, the cavalry attacked.
